The Radio Shack catalog lists the LM2902 IC's out @ .99¢ ea. I also believe the LM2901's are the same price as well. A while back my idle speed ECU died on me. replacing the IC's is not a problem, but what is is that I'm not sure about how one of the chips is soldered in. It looks like someone removed part of the solder from 2 pins on one of my chips. So needless to say I'm unsure if these 2 pins need to be soldered into place. I'm @ work right now, so when I get home tonight I'll place the board on my scanner & upload the pic. -Robert vin 6585 (The DeLorean from hell.) --- In dmcnews@xxxxxxxxxxx, "John Hervey" <dherv10@xxxx> wrote: > Chris and Group.
